MIMI! WWK @W4/SLM ORNEY Patented `uly 4, 1939 UNITED STATES PATENTOFFICE APPARATUS FOR USE WITH COFFEE 2 Claims.

This invention relates to apparatus useful in the preparation of coffeeor other similarly prepared beverages.

It is an object of the invention to provide an apparatus for useparticularly with the now popu lar type of vacuum coffee makers whichwill serve as a heater for the coffee after it is brewed and as a heaterfor the water used in its preparation.

Another object of the invention is to provide,

in combination with the apparatus described above, a cushion support forthe glass coffee dispensers which will insure against breakage of thelatter should t'hey be set down hard.

The invention possesses other object and features of advantage, some ofwhich, together with the foregoing, will be specifically set forth inthe detailed description of the invention hereunto annexed. It is to beunderstood that the invention is not to be limited to the particularform 'gq thereof shown and described as various other embodimentsthereof may be employed within the scope of the appended claims.

Referring to the drawing:

Figure 1 is a side elevational View, partly in 5, vertical section so asto more clearly disclose the interior construction of the apparatus ofmy invention.

Figures 2 and 3 are, respectively, a top plan view and a sideelevational view of the cushion :1o for the coffee container.

In detail, the apparatus comprises a centrally apertured rectangularbase having a rim 4 provided in its top surface with a depression 6 andntted 'with legs 'I which space the base above :.25 the surface 8 of thesupport upon which it may be mounted. Gas burners of the type comprisinga main burner 3 and a pilot light II are positioned below the base.Mounted on the base is a tank, for containing a quantity of water I2,

4.3 comprising a side wall I3, a bottom plate I4 having a peripheralflange I6 soldered or otherwise secured to the side wall along the loweredge of the latter, and a cover plate II having a marginal flange ISwhich fits loosely within the top open- .;,3 ing of the tank. Openinginto the tank through `the cover plate Il is a supply pipe I9, throughwhich water may be admitted to the tank, and a valve 2i is provided inthe pipe so that the water flow may be controlled or stopped. A faucet22 is provided, adjacent the bottom of the tank, through which the waterI2 may be withdrawn, and a gauge glass 23 serves to indicate the heightof the water remaining in the tank.

The bottom plate I4 is provided with apertures,

centered over each of the burners, in each of which is mounted acentrally bored collar 24 having a flange 26, which is soldered orriveted to the tank bottom so as to provide a fluid-tight joint, andthreads in the bore thereof which engage the threaded bottom end of atubular duct 2'I extending upwardly through the tank. The cover plate Ilhas therein circular recesses 28, each of which is provided with acentral aperture through which the threaded upper end of a duct 2lextends and nuts 29 and washers 3| are provided on the duct forrendering the connection of the latter with the cover plate fluid-tight.It will be seen that, as the cover plate is connected to the bottomplate through the medium of the ducts 27, no further means are necessaryto maintain the former plate on the tank. Since there will beconsiderable steam generated within the tank when the water I2 isheated, the provision of a loose t between the marginal flange I8 of thecover plate and the side wall I3 of the tank allows for venting of thetank to permit the steam to escape.

Seated within each of the cover plate recesses 28 is a cushion memberwhich provides a support for the glass container 32 forming the bottomsection of the well known type of vacuum coffee maker. This cushionmember, which is shown in detail in Figures 2 and 3, comprises acentrally apertured bottom plate of sheet metal having an upwardlyextending peripheral rim 34 from the top edge of which extend radiallyinwardly toward the center of the plate 33, a plurality of resilienttabs S6 each of which is shaped to conform with the bottom curvature ofthe container 32 so that all of the tabs mutually provide a K dishedseat for supporting the container. Heretofore, in apparatus of thischaracter, the receptacle, equivalent to the cushion member of thepresent invention, has been a solid casting possessing no resiliencewith the result that quite often, in setting down the container 32 alittle harder than usual, the latter will, upon coming in contact withthe unyielding receptacle, be broken and shower the user with scaldingcoffee. The provision of the resilient seat for the coffee container inthe apparatus of my invention obviates this danger to a great extent.

In primarily heating the water I2, the containers 32 are removed and themain burners 9 are turned on until the water reaches the boil- D ferenceof some of their heat to the water l2 and maintaining the latter nearthe boiling point and then emerging from the upper end of the ducts andpassing outwardly under the containers so that the coffee in the latterwill be mainw tained in a heated condition.

Having thus described my invention in detail, what I claim as new is:

l. A support for a container to be heated over an end of a burner flue,comprising an annular member having thereon a plurality of curvedresilient arms extending inwardly and each shaped to mutually provide adepression in which said container may be seated.

2. A support for a container to be heated over an end of a burner flue,comprising an annular member having thereon a plurality of curvedresilient arms extending inwardly and each shaped to mutually provide adepression conforming in contour with a peripheral portion of saidcontainer and in which said container may be seated. 10
